For any particular PBN operationa sequence of RNAV and RNP applications can be used
Safety Efficiency / Fuel savings

Benefits of RNP
Why RNP?
Conventional Procedure
• Truth used to be an ILS localizer and glide slope beam
• The airplane flies a ground based signal that is always in the same position relative to the runway
RNP Procedure
• Truth is the database
• The airplane flies to the waypoint, right or wrong
RNP Approach requires highest quality dataWhy?
Virtually all worldwide procedures are available inon-board navigation databases
In a world based on conventional navigation:• Pilots have a “Ground Truth“• FMS/GNSS provide guidance to a ground based
navaid signal
Consequences
In a world of Performanced Based Navigation:
Consequences
• “Ground Truth” is not available• Nav system provides guidance to waypoints,
wherever the database says they are• Dependent on accurate data• Data = mission critical information
The airplane flies to the waypoint, right or wrong
